SLC, PLC5 & Micrologix Family

The DF1 IO Server of eWON provides 3 features:

  • Poll items in SLC50x, Micrologix and PLC5 controllers using PCCC requests.
  • Forward PCCC requests from EIP (TCP/IP) to DF1 bus and thus, act as an adapter between EIP and DF1. Using that feature, it is for example possible to access a PLC connected to the eWON’s DF1 link by connecting RSLogix 500 using RSLinx TCP driver started with the eWON IP address as destination.
  • Poll DH+ device using ControlLogix gateway

Remote maintenance available.

Look in the table below to find which IOServer (DF1 or ABLogix) you need to use to connect your Rockwell device and the minimum firmware version required.
